Anybody got a clue where the MacPro6,1 power / sleep setting went?

The only thing I can set is the "Turn display off after" slider.

On my old MacPro2,1 there were two settings:

  • Computer sleep
  • Display sleep

More frustrating, my PC goes into sleep/standby even when im running something like Terminal with SSH session. On the old system you could set a different sleep for the computer (i'm fine my screen goes to sleep in 5 minutes).

$ pmset -g

    nothing, my mac is just a few days old. I guess since it doesn't have a HDD (but SSD) Apple thinks we don't need it?

  • That is funny :) you should be able to set it, and not have Apple boss you around. run the pmset -g in terminal to see your current settings.

It is probable that Apple no longer feels the Computer sleep and Display sleep options are required.

The new Mac Pro has no spinning hard disk drives and has a modern power management system that can manage itself.

I suspect you can change settings using low level tools like pmset, but that those settings will be ignored.

Staying Awake

To keep your Mac awake during long running processes, use the Terminal.app command caffeinate:

  • Thanks, right (makes sense). Any idea how i can keep it awake while my screen can goto sleep (like with a huge download) ?

  • @Rogier terminal ping -i 300 google.com keeps the network alive till you kill it.

  • To keep your Mac awake during a long download, use the dssw.co.uk/reference/caffeinate.html command e.g. caffeinate. Ideally, your downloading application will register a 'do not sleep assertion' and this will avoid idle time sleep interrupting your download. Jun 27, 2014 at 14:41

  • @GrahamMiln, thank you for pointing out caffeinated. I wrapped caffeinated inside my bash_profile, so when starting a ssh session it automatically "caffeinates" ssh.
